^a A: Functionally characterized TEs; B: TE does not group near characterized TEs and/or no organism lipid profile information is available; C: TEs cloned from organisms known to produce MCFAs; D: Organism's lipid profile used and predominant fatty acid constituents identified in the organism are listed in parentheses.

^b The data are represented as mean ± standard error (n = 4).

^c All but the three C. nucifera sequences were codon-optimized for expression in E. coli.

^d Transit peptides were removed from all plant sequences.

^e Acyl-ACP TEs with known crystal structures.

TEs were expressed in E. coli K27, and free fatty acids (FAs) that accumulated in the medium were analyzed by GC-MS.
